چکیده مقاله:

Sago hampas was chemically modified through esterification process to adsorb both laboratory and commercial synthesized ZnO nanoparticles from water in a batch adsorption studies. The esterified sago hampas (ECSH) as a biosorbent w:as char:acterized using Energy dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET) technique s. Investigating the effect of pH, contact time, initial sorbate ion concentration, temperature and sorbent mass were carried out where adsorption parameters were analyzed using Langmuir, Freundlich and Temkin models. The correlation between kinetics of adsorption and tgr rate order of ZnO nanoparticles on ECSH were also determined. The adsorption of the ZnO nanoparticles was found to increase with increasing contact time with the attainment of equilibrium at ۱۰۰th minutes with maximum removal efficiency of ۸۵.۵% (۰.۰۳۶ mg/g) and ۸۹.۶% (۰.۱۰۶ mg/g)  ZnO nanoparticles for laboratory and commercial synthesized ZnO from aqueous solution. An optimum pH of ۸ with adsorbent dose of ۲.۰ g at a temperature of ۵۰ oC gave good results of  ZnO nanoparticles removal. The equilibrium data for both sorbate solution fitted well for both Langmuir and Freundlich isotherm models. From the Langmuir model, ECSH recorded greater sorption capacity of ۰.۲ mg/g and ۰.۶ mg/g for both laboratory and commercial synthesized ZnO nanoparticles respectively. The kinetic studies showed pseudo-second order model as the best fitted for the sorption of ZnO nanoparticles for both synthesized samples.
